STMicroelectronics 74V1G08CTR

Overview

74V1G08CTR from STMicroelectronics is a single 2-input AND gate in SOT323-5L package, operating from 2V to 5.5V, with 3.8ns typical propagation delay at 5V, ±8mA symmetrical output drive, and input tolerance up to 7V independent of supply-enabling robust 5V-to-3V level translation in portable logic interfaces.

For engineers reviewing the 74V1G08CTR datasheet, 74V1G08CTR pinout, 74V1G08CTR application, or 74V1G08CTR equivalent, key selection criteria include its rail-to-rail input voltage acceptance (0–7V), power-down protected inputs, sub-10ns AC timing across temperature, and guaranteed 1µA max ICC at 25°C for ultra-low static power in battery-sensitive designs.

Technical Context

This device implements a two-stage buffered CMOS AND gate using sub-micron C2MOS technology, delivering balanced tPLH/tPHL delays and high noise immunity (VNIH/VNIL ≥28% VCC). Its input structure accepts voltages from –0.5V to +7.0V regardless of VCC, enabling safe hot-swap and mixed-voltage interfacing.

The output stage provides symmetrical sourcing/sinking capability (≥8mA at 4.5V) with stable VOH/VOL across VCC = 2–5.5V and temperature (–55°C to +125°C), while internal power-down protection prevents back-driving current when VCC = 0V.

FAQ

Can 74V1G08CTR safely interface a 5V sensor output to a 3.3V microcontroller input?

Yes. Its inputs accept 0–7V regardless of VCC, so a 5V sensor output can directly drive Pin 1 or 2 while VCC = 3.3V. The output swings rail-to-rail (0V to 3.3V), ensuring compatible logic levels for the MCU. No external resistors or level shifters are needed.

What is the maximum capacitive load this device can drive while maintaining specified tPD?

The datasheet specifies tPD with CL = 15pF and CL = 50pF loads. At 5V, tPD remains within spec (≤8.0ns max) up to 50pF. For heavier loads (>50pF), propagation delay increases linearly-designers should limit trace+input capacitance to ≤45pF for guaranteed timing compliance in high-reliability systems.

Does 74V1G08CTR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be tied to VCC or GND directly. The device features power-down protection and high-impedance inputs with ≤1µA leakage, so floating inputs are not permitted-tying them avoids undefined logic states and potential shoot-through current in cascaded stages.

How does the 74V1G08CTR perform under cold temperature conditions (–40°C to –55°C)?

It is fully specified from –55°C to +125°C. At –55°C, tPD increases to ≤10.0ns (vs. 8.0ns max at 25°C), VOH drops by ≤0.1V, and ICC remains ≤20µA. All DC and AC parameters meet datasheet limits, confirming suitability for arctic-grade industrial and automotive deployments.
